I had a Neo for a couple of months and I would get about three days battery life.
It was ok but it really looked like it wasn't going to get any decent apps for it, so I switched to the G watch.
On the Gear, I miss the Home key and the longer battery life than the G watch.
The G watch works better with notifications but if they aren't from Google Apps, you only get the title of the notification and a small amount of the content.
You also can't change the font size on the G watch and to be honest, it's just too big when scrolling through an email.
I'm very hopeful that the limitations on notifications will be addressed as apps are updated to integrate with Android Wear. I really couldn't see this happening with the Gear as the audience is just too small for the app developers to bother.
Also, I'm looking forward to some decent extensions of existing apps that actually work well with Android Wear!
